inspect.getattr_static is currently not identifying data descriptors the right way. Data descriptors are defined by having a __get__ attribute and at least one of the __set__ and __delete__ attributes. Implementation detail: Both __delete__ and __get__ set the same slot called tp_descr_set in CPython. I have attached a patch that fixes the issue IMO. |

This is not a duplicate. It is related to https://bugs.python.org/issue26103, because __get__ is not required anymore for an object to be a data descriptor. The current code on master (of inspect.getattr_static) still thinks a descriptor has both __get__ and __set__ set. Since issue #26103 has been fixed, it's now clear that my patch is slightly wrong, but I'm happy to fix that if someone is actually going to review it. |

Can you give an example of where getattr_static() is not doing what you expect? |
